In Flexitive, when you add a new element to your design, that element will be added to all activated sizes. By adding your elements to all activated sizes, Flexitive makes the entire design process shorter.
When editing a size, you can choose what sizes you want a newly added element to appear on. Using the Visibility settings in the Customize Panel, you can set an element to hide an on a particular size, on all other active sizes, or by portrait and landscape orientation.
You can see the elements you’ve hidden on your canvas using the ‘Show Hidden Layers’ toggle in the Layers panel.
